ADJUSTABLE CHAIR.

. Specification of Letters Patent.

Application filed November 26, 1915. Serial No. 63,514.

To all whom, it may concern Be it known that I, Ro'r N. GAGE, a citizen of the UnitedStates, residing at Sturgis,

Michigan, have invented certain new an useful Improvements in Adjustable Chairs, of which the following is a specification.

This invention relates to improvements in adjustable chairs. I

My improvementsrelate particularly to adjustable chairs of the type shown in the patent to Borgart No. 1,087 ,526, dated Feb. 17, 1914, and is in some respects anv embodiment of and an improvement upon certain features of the structure there illustrated. The main object of this invention is to provide in a chair having an adjustable back a metallic fixture extending. between and adapted to be mounted as a unit on the front and rear rails of the chair frame, said fixture also constituting a brace for the chair frame.

Further objects, and objects relating to details and economles of construction and operation will definitely appear from the detailed description to follow.

'I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims. 1

'A structure constituting a preferred embodiment of my. invention is illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is an inverted View of a chair embodying the features of my invention, the

seat and back cushions being omitted and a portion of the back broken away.

Fig. II 'is a detail vertical section of the structure shown in Fig. I on a line corresponding to the line 2-2 of Fig. I.

Fig. III is an enlarged detail view partially in vertical section on a line corresponding to line 3-3 of Fig. I.'

Fig. IV is an enlarged detail view showing further details of the back'supporting mechanism partially in section on a line corresponding to line 4.-4 of Figs. I and II.

Fig. V is a detail of the actuating mechanism partially in section on a line corresponding to line 5-5 of Figs. 1 and III.

In the drawing similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referrlng to the drawing 1,1 represents the front posts and 2, 2 the rear posts which are extended to form the front and rear legs of the chair. The posts are connected by the side rails 8, front rail 4: and rearrail 5, thus forming the main frameof the chair.

On the upper ends of the posts are-arms 6 WlllCll are in effect part of the main frame.

The back comprises side rails 7 and connecting cross bars 8. This back is pivotally mounted on the frame, the back pivots not being shown as suitable T pivots are well known in the art. I

The seat, designated generally by the numeral 9, is of a suitable structure adapted to rest on the main frame. The back is in practice provided with a suitable cushion 10. The back is provided with an arm 11 projecting downwardly within the frame in front of the rear. rail 5. The back adjust ing, and supporting means comprises a casing and supportingfmember 12 which is preferably formed of sheetmetal and channel-shaped in cross section to provide spaced side members 13, as best shown in Fig. IV.

The casing member 12 is provided with laterally turned front end and with diverging arms 15 at its rear end terminating in laterally turned attaching ears 16. The casing memberis arranged between'the front and rear rails of the frame and is secured thereto by screws 17 through its said casingmember being formed of metal and shaped as stated, constitutes an effective supporting bar and brace for the frame. Supported within and guided by the casing member is a slide 18 having'a plurality'of ball seats 19 in its under side. The-slide has preferably a sliding fit within the top of the casing member as illustrated.

. A .retaining member 20 for the clutch or pawl ball 21. is arranged between and secured to the side members of the casing memberby means of the bolts 22. The re taining member is preferably arranged so as to constitue a support for the slide; See Fig. III. The retaining member has a chamber 23 for the ball opening at the top and a transverse slot or way 24: below the chamber and opening into the same so that attaching ears 14 at its attaching ears. The

the actuating member 25 may be actuated in actuating member is in the form of a bar,

its outer end being pivoted at '27 to-one arm-- vof the bell crank lever 28, which is pivot- "ally" mounted at 291011: the "crossbar An actuating. spri g; 28 "Ais connected tofthe upwardlji projebtingarm. of the bell crank 6 -1T i i f n 6 this? sw r? rails facingdownwardly, j' a downwardly is seeurfchto the' casing'frnember' byfone of the ibolt's'fffii Itsfouter-"end is secured. to"
